FITTING FOR WATER-HEATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 379,269, dated March13, 1888.

Application filed January 2, 1885.

To aZZ whom it may concern:

Be it known that I, ALLEN P. ORE UE, of New York city, county, andState, have invented an Improvement in Fittings for \Vaten HeatingApparatus, of which the following description,in connection with theaccompany ing drawings, is aspecification, like letters on the drawingsrepresenting like parts.

My invention relates to a pipe-fitting or multi-passage cover providedwith pipe-eonnections and a controlling-cock to be used in connectionwith waterheating apparatus, such as are usually employed in connectionwith stoves or ranges for heating and circulating water for domestic orother purposes.

The fitting forming the subject of the present invention is adapted tobe connected with the boiler or hot-water reservoir, and contains twoindependent passages leading from the interior of the said reservoir andterminating in two independent branches, one of which may be connectedwith the pipe or tube leading to the heater and the other of which maybeconnected with a discharge or sediment pipe, the said passages andbranches being combined with a cock located atthe junction thereof, bywhich the said waste or sediment passage may be closed and the reservoirplaced in connection with the heater, or by placing the said cock inanother position communication with the heater may be cut off and theinterior of the reservoir be connected with the sedimentpipe for thepurpose of discharging the sediment from the reservoir, or by placingthe said cock in a third position communication may be cut off from thereservoir and connection made between the heater and the waste-passagefor the purpose of removing sediment and withdrawing the water from thesaid heater.

Figure 1 is a vertical section of a reservoir and connected appliancesembodying this invention, the ,multipassage cover and pipes and tubesbeing in elevation; Fig. 2, a'longitudinal section of the cover andpipes connecting the reservoir with the heater and sediment-pipe; andFig. 3, an under side view of the said cover and pipes, parts of thebranches being broken out to show the stop-cock.

The reservoir a is provided with top and bottom plates, b 0,-havinglarge openings for Serial No. 151,764. (No model.)

the reception of multipassage covers cZ-sucl1 as described in myapplication, Serial No. l5l,762- having suitable tubular projectionstowhich the various pipes to be used in connection with the said reservoirwill be joined in the usual manner.

The cold-waterinlet pipe (2 is provided with a controllingvalve, 6,having a vent-pipe f, extended to the upper portion of the reservoir. Asshown in this instance, it is substantially the same as in anotherapplication filed herewith, Serial No. 151,763, wherein the same is morefully described and claimed. The devices herein shown, and common to thesaid application, are not herein claimed.

The water is caused to circulate from the reservoir through a passage,ina compound fitting, h, shown in thisins'tance as forming an integralpart of the multipassage cover d, having connected or cast with itsother branch tubular projections t" i", &c., adapted to be joined withother pipes passing into thelower end of the reservoir. 1

The fitting h has at its lower end a branch,

h, on the same side as the passage g, and it also contains anotherpassage, and branch h and is provided with a cock, h*, at thejunction ofthe said passages.

The passage 9 for the-circulation of water preferably has, as acontinuation of it, a short pipe, k, extending up into the-reservoir ashort distance, as shown in Fig. 1. and preferably provided with alateral mouth, k into which the water is received from a point above thesediment which accumulates in the lower portion of the reservoir.

In the operation of the water-heating apparatus the cock h, which isprovided with a handle, 71 (see'Fig. 1,) is normally in the positionshown in Figs. 1 and 2, closing the lower end of the sediment-passage gand the branch If, and connecting the passage 9 with the branch h, whichlatter is joined by a pipe, m, with the heater, (indicated at c, Fig.1,) in which the water is heated and caused to rise, and from which theheated water is delivered through a circulating'pipe, 0, leading to theupper end of the reservoir, the pipe being shown in this instance asentering through the cover d at the lower end of the said reservoir bymeans of the elbow or passage i, which connects portions of the pipeowithin and outside the res ervolr.

The heated water may be withdrawn from the reservoir through the pipe p,leading from its upper end, or through the pipe )9, leading from theupper end of the reservoir down through the interior thereof and passingout through the cover d at the lower end of the reservoir.

The sedimentpassage 9 opens directly from the cover (I at the lowestpoint in the reservoir, and it will be seen that by turning the cock khalf around the passage 9 and branch h will be closed and the passage 9connected with the branch hflwhich is provided with an orifice, k (seeFig. 1,) or is connected with a wastepipe, so that the water may bedrawn directly from the reservoir, carrying with it the sediment whichmay have accumulated near the bottom thereof, thus cleaning thereservoir of sediment.

By turning the cook 71; one-quarter of a turn in the direction of thearrowindicated thereon both passages g y will be closed at their lowerends and the branches h h be connected, so that the water may flowthrough the circulat ing-pipes 0 m and the heater, escaping at theorifice h thus removing sediment from the heater; or by closing theinlet-pipe d and admitting air to the reservoir through one of the pipes19 or p the water may be withdrawn from the hot-water-delivery pipe 1)and from the circulating-pipes 0 m and the heater n, leaving the body ofthe reservoir filled with water, thus protecting the hot-water-deliverypipep, the heater, and circulatingpipesfrom danger of bursting byallowing water to freeze in them, and that without withdrawing the Waterfrom the reservoir.

It will be seen that the passages g g and branches h h are similar toone another, so that if the reservoir is to be placed at the other sideof the heater, as is sometimes necessary, the pipe k may be screwed intothe passage g'and the branch if connected with the pipe m, and thebranch h used as a waste or discharge passage, aud the handle h of thecock will still re main at the front,where it may be readily operated.

The compound fitting h need not necessarily form apartof the cover d,butis complete in itself, and maybe connected with the reservoir in anysuitable manner, as by soldering or screw-threads, or as an independentcoupling device.

I claim- 1. The boiler or reservoir fitting composed of the pipe h,having independent passages g g and two branches, h h substantially at aright angle to the pipe h, and of the cock h located at the junction ofthe passages g g with the branches h h substantially as described.

2. The combination, with a heater and a range boiler or reservoir,of acover having an attached pipe provided with two independent passages, gg, and having two branches, h h", and the cock lz intersecting thepassages g g and the branches II. It, change of position of the cock hpermitting the discharge of sediment or water from the boiler or thewith dra wal of the sediment or waterfrom the heater, substantially asdescribed.

3. The combination of a range-boiler orhotwater reservoir, heater, andcirculating pipes or ducts connecting the same, with a fitting having apassage, 9, and branch h, constitutinga part of the circulating-duct,and a discharge or sediment branch, Jr, and the cock h, controlling thesaid passage and branches, whereby communication may be cut off betweenthe lower portion of the reservoir and circulatingpipes, and the latterconnected with the discharge branch for the withdrawal of the contentsof the circulating-pipes and heater without emptying the reservoir,substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesscs.

ALLEN P. CREQUE.
